HEELlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 543,682, dated July 30, 1895. Application led November 30, 1892l Serial No. 453,641. (No model.)

To all whom t may concern.-

Be it known that I, CHARLES W. GLIDDEN, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Heeling-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings representing like parts.

1o This invention is intended as an improvement on the class of machine represented in United States Patent No. 468,279, dated February 2, 1892. In the machine described in the said patent the drivers used to drive the r 5 nails during the heel-attaching operation are stationary and the nails are driven by a force applied to the shoe-support, and during this operation of attaching the heel, besides the power necessarily expended to effect the driv-v zo ing of the nails, the machine has also to cornpress powerful springs which are afterward released and permitted to act to effect the top-lift-attaching operation. Itv will also be seen in the machine'referred to, where the heelattaching operation is effected by or v through the movement of the shoe-support, that any material differences in thickness of heel or hardness of stock will require greater power, and hence when such variations exist 3o the power required to rotate the main shaft of the machine will constantly vary. f

It has been found that nails may be driven into leather with less liability to run aside or cripple When the driving force is a quick 3 5 sharp blow rather than slow pressure. 1 have therefore in my invention aimed to more evenly distribute the power required to operate the machine, so that each operation may be effected .with the minimum application of power and as evenly distributed as possible through each cycle of operation, and I have also provided for attaching the heel, as Well as' the top lift, with a sharp quick blow, one following the other.

In my invention, wherein the heel-support is moved simply to put the heel and sole firmly in contact prior to the heel-attaching operation performed by a quick blow of only the necessary strength to drive the nails, the

5o strain exerted on the last is so reduced that a wooden last may be safely used, which is of great importance to manufacturers.

ever, omitted. Fig. 24 is a vertical central section of Fig. 1', Figs. 2 and 2a making upa central section. Fig. 3 is a section on the line or', Figs. l and 2. Fig. 4 is an under side view of the templet and top-lift carrier and some of their co-operating devices.

The framework is made up essentially of side pieces A A, a crossbeam A', a table A2, and a cross-rod A. The side pieces have, as shown, suitable boxes, as A4 A5, in which are 70. clamped rmly the guide-rods A6, on which slides the cross-heid A7. The cross-head A7 is connected, as-herein shown, to arod B, guided in a suitable bearing in the table A2, the lower end of the said rod being suitably jointed at B to an adjustable link B2, in turn jointed at B3 to its actuating mechanism B4, in this instance shown as a foot-treadle, pivoted at B5. Thetreadle shown is represented as being acted upon by a suitable spring, as B6, it serving to normally depress the crosshead. The cross-head is provided with asuitable guideway, as 2, to receive a main slide B8, itin turn being grooved transversely for the reception of a cross-slide B9, suitably shaped to receive a.lastpost-, as B10, having a suitable last'pin B42.

The parts thus far referred to by letter are and may be of usual shape, and instead of the particular parts shown I may use any usual equivalents.

The cross-beam A has erected on it a tubular or sleeve-like guide C for the driver-bar C', herein represented as a rod with a tubular extension 3, having a suitable head -t for the reception of the driver-plate C2 carrying the. gang of drivers C3. The driver-bar is surrounded by a strong spiral spring C4, resting at its lower end upon a suitable shoulder 5 of the driver or a part thereof, the said spring roo being acted upon at its opposite end by an adjusting device C5, herein represented as a tubular nut, it also serving as a bearing or guide for the driver-bar. The driver-bar has cooperating with it a suitable lifting device, shown in `this instance of my invention as a lever D pivoted at D and having joined to it at 6 a link D2, slotted at its upper end, as shown at 7, to receive apin 8 carried by a block D3, clamped upon the driver-bar by a nut D4.

When the outer end of the lever D is elevated, as shown in Fig. 2, the lower end of the slot 7 in the link D2, by acting on the pin 8, lifts the driver and compresses the spring C4, and when the driver-bar is in its elevated position a suitable locking device, shown as a1 latch a, having its fulcrum on thepin 8, drops into engagement with a projection a' of the sleeve C. As the driver-bar is lifted, as stated, it also lifts a block E located above it, (see Figs. 1 and 2,) and said block lifts with it the rods EE, guided in the cross-beam A and having attached to their lower ends the teinplet I), it having suitable holes l0 for nails and` for the passage of the drivers C3.

The rods E are surrounded by suitable spiral springs h2, which rest on shoulders b3, the said springs at their other ends'being acted uponby spring-adj usters b4, shown as tubular nuts, screwed into ears at the top of the sleevelike .guide C, said nuts also acting as guides for the said rods, the adjustment of the nuts regulating the force of theblow employed in attaching the top lift.

The block E has co-operating with it a locking device, as e, which, when said block is elevated, engages a projection, as e', of the sleeve C.

After the driver-bar and. the block E and their attached parts have been elevated, as described, and locked in their :elevated posi-` tion, the lever D may descend, the slot? per mitting such descent, so that the `pin 8 has` free travel in said slot after the locking device has been unlocked and while thedriverbar is descending.

The templet-plate has pivoted to it at 12 a heel-holder b', it having a series of holes coinciding with the holes 10 in the teinplet, said heelholder (it really forming in one position a continuation of the templet) being represented as hinged or pivoted, in orderthat itl may be dropped down, say, for ninety degrees, for the convenience of the operator in apply-` ing a loaded heel and a top lift, in order that the adjustment ofthe slides BB and B9 will see they may be put onto a shoe.

The operator will insert into the holes 101 of the heel-holder the heads of the nails pre` viously partially driven into the heel, the said` nails exerting sufficient friction in said holes f to hold the heel in place while the heel-holder is being turned up into the position shown in Figs. l and 2.

this instance bored for the reception of guiderods b2, attached at one end to suitable ears b3 of a top-lift carrier, shown as a .plate b4, having mounted upon it suitable jaws, as b5, controlled by suitable springs which normally act to cause the jaws to grasp the side edges of a top lift b. (Shown by dotted lines, Fig. 4.)

the position shown in the drawings.

The heel-holder plate b is inl C, said ring having, as shown, two cam-sur `faces d d2, which `contact respectively and successively with the locking devices a and c, in order that the driver may first be tripped to attach the licei, and then the springs b2 be permitted to act to attach the top lift, as will be described. This unlocking device has a suitable operating-handle, as cl3, and in operation said handle to unlock the locking flevices will be turned in the direction of the arrow, Fig. 3.

This invention is not limited to the exact form of locking devicesorof releasing device co-operating therewith, and it `will be obvious that I may, `without invention, actuate the shoe-support by or 'from a shaft, as in the patent referred to, and this invention is notiimited to the exact form of driver-lifting devices, as any other usual or suitable devices for such purpose may be used.

Referring to the drawings, wherein the p driver-.bar is represented as already elevated,

I will fnow describe the operation of the maf chine. In this position it will also be supposed that the heel-holder b is hanging ver tically fromits pivotal point l2. The operator will put the ends of the partially-driven nails of a loaded heel into the holes in the plate b and at the same time will'put the top lift h6 in `position between the jaws of the toplift carrierand will turn the plate b up into Fig. l shows by dotted lines a heel in position, and Fig. 4 shows the top lift. The operator will now take a lasted shoe having its sole properly attached, said shoe being preferably on a wooden last, and will mount the last upon the heel-pin B12, so that the last is held firmly. The operator will then cause the cross-head AT containinga shoe-support to be lifted, and by `that the heel end of the sole comes properly against the seat .end ot' the heel, and by the time the joint contrivance which elevates the cross-head A7 is in its upper position 4the sole and heel will have been brought firmly together, so as to avoid any slipping during the attaching operation. The operator will next engage the handle d3, turn it far enough for its cam d to meet and throw oit the locking device a, thus letting thespring c4 `act and throw the driver-bar down with aquickblow, causing the driver c3 to pass through the templet-plate, act upon the heads of the partially-driven nails, and drive the nails sufllO ciently to attach the heel to the sole, leaving, however, preferably a portion of the heads of the nails protruding, in order that the top lift from the plate b far enough to leave a space suflicent to let the topglift carrier be put into the position immediately below the driverholes in the templet,this movement being preferably effected by or through suitable springs f, best represented in Fig. 4, attached at one end to projectionsf of the plate b and to projections f2 of the top-lift-carrier plate, the top-'lift carrier during the operation of driving the nails from the heel into the sole resting at each time with one edge against the heel, the latter resisting the pressure of the top-lift carrier by the partially-driven nails, entering through the holes 10. The top-liftcarrier plate having been broughtinto correct position, the further movement of the u nlocking device in the direction of the arrow, Fig. 3, will 'cause its cam-surface d2 to act upon and release the locking -device e, thusl permitting the springs d2 to operate to throw down quickly the templet and its attached parts together with the top-lift holder, the shoe support having been lowered sufficiently far to enable the springs to move the templet and its parts far enough to make a spanking blow sufficient to impale the top lift upon the heads of the partially driven nails. This done, and the shoesupport havingy been brought into its lowest position and the driver-bar having been again elevated by or through suitable devices, as described, the operator will remove the last and shoe from the last-holding pin and will apply a new shoe and repeat the operation described.

Having described my invention, what I claim as new, and desire to secure by Letters Patent,`is-

l. In a heel nailing machine, the following instrumentalities, viz;-a driver -bar having an attached series of drivers; a spring to actuate the driver-bar; a locking device to keep the driver-bar in position withits spring com` pressed; a templet; a carrier therefor; a suitable spring to actuate the templet; a locking device to retain the templet carrier with its spring in compressed condition,and a releasing device to successively release the locking devices and permitthe spring of the driverbar to iirst' act to actuate it to drive nails, and then to permit a spring of the templet to operate to actuate the vtemplet during the opertion of attaching a top-lift, substantially as described. d

2. In a heel nailing machine, the following instrumentalities, viz;--a driver-bar having an attached series of drivers; a spring to actu- .ate the driver-bar; a locking device to keep the driver-bar in position with its spring compressed; a templet; a carrier therefor; a suitable spring to actuate the templet; a locking ating means for the shoe support whereby f the latter may be moved to put the sole of the shoe and the heel to be attached to it, in iirm contact prior to the heel attaching operation, substantially as described.
